The picosecond laser output laser pulse width is 10ps, the wavelength is 532nm, and the repetition frequency is 100 kHZ.
The principle of the glass containing the quantum dots is that the glass consists of sodium silicon carbon, and the power density of 250kHz picosecond laser is very high after being focused by a picosecond laser induction method, the temperature of a focused area is as high as thousands of K, the glass has very strong heat effect, the glass is melted in a small range, and anions and metal cations are combined to form a small core under the action of heat and grow continuously. Meanwhile, due to the reaction with space selectivity induced by the nonlinear interaction of the picosecond pulse laser and the glass, a controllable three-dimensional microstructure can be formed in the transparent glass.
Compared with the high repetition frequency femtosecond laser induction method at the present stage, the method for inducing quantum dots in glass by using picosecond laser has the following advantages:
1. the picosecond laser is far cheaper than the femtosecond laser and has good stability.
2. Picosecond lasers are much faster than femtosecond lasers in terms of processing efficiency due to the obvious thermal effect.
3. The influence of picosecond laser on the aspects of absorption, refraction and the like of glass in a processing area after quantum dots are induced in the glass is far less than that of femtosecond laser.
